Patent GB-467085-A (GB)
Title: Manufacture of indulines
IPC: C09B17/00
Filed: 1935-11-11
Abstract: Water-insoluble indulines are made by substituting for aniline in the hitherto usual "melts," i.e. in the reaction between aniline, its hydrochloride, and nitrobenzene used as an oxidizing agent or an aminoazobenzene used as a dehydrogenizing substance, an alkoxy-substituted amine of the mono- or diphenylamine series. Alternatively, instead of the nitrobenzene and the alkoxydiphenylamine there may be used an alkoxy-substituted primary phenylamine, and a nitrobenzene containing a nuclear substituent capable of being exchanged for an amino group upon reaction with a primary amine (e.g. halogen, -NH2, -OCH3, or OC2H5), or an alkoxy-substituted mono- or poly-nitrodiphenylamine.  The reaction may be conducted in presence of a heavy metal salt such as the salts of cobalt, nickel, tin, cadmium, mercury, antimony, strontium, iron, copper, chromium, or aluminium with inorganic or organic acids, the salts with complex bound heavy metals being preferable.  The reaction may be carried out under increased pressure when the product dissolves easily in ethanol.  The products generally have improved solubility in lower alcohols, esters, and nitrocellulose and acetyl cellulose lacquer mixtures.  In examples, dyestuffs are made by heating melts containing phenetidine mixed with (1) 2-chloro-1-nitrobenzene, and ferric chloride or cupric acetate and ferric chloride or acetate, (2) 4-chloro-1-nitrobenzene, (3) sodium 6-chloro-3-nitrobenzene - 1 - sulphonate, (4) 4<1> - ethoxy - 2.4 - dinitrodiphenylamine and hydrochloric acid, (5) 4-chloro-1.3-dinitrobenzene, (6) nitrobenzene hydrochloric acid and either ferric and cupric acetates or ferric chloride only, (7) phenetidine hydrochloride and anisole-(2-azo-5)-2-aminophenol-methylether or an equivalent quantity of aminoazobenzene, (8) phenetidine hydrochloride, 2-nitraniline and cupric and ferric acetates, (9) phenetidine hydrochloride, 2.4-dinitraniline, cupric acetate and ferric chloride, (10) 1.3-dinitro-4-chloro benzene and copper powder. Also in examples, anisidine is heated with 2.4-dichloro-1-nitrobenzene.  Other nitro-bodies specified are 3.5-dichloro-1-nitrobenzene, 2-chloro-3.5-dinitrobenzoic acid, phenyl (5-chloro-2-nitrophenyl)-ether, 2.6-dinitraniline, 2-nitrophenetole, 2.4-dinitroanisole, 2.4-dinitrophenetole, 2-methoxy-3.5 - dinitrobenzoic acid.

Title: Improvements in or relating to the manufacture of electric capacitors
IPC: H01G4/30
Filed: 1969-06-24
Abstract: 1,268,962. Capacitors. SIEMENS A.G. 24 June, 1969 [25 June, 1968], No. 31703/69. Heading HIM. In a method of manufacturing capacitors wherein dielectric strips and metal layers are assembled to form a parent capacitor which is divided into individual capacitors, the metal layers at the partition faces are provided with insulating boundary zones by a heat treatment of these faces, and the formation of the insulating zones is enhanced by the presence, in at least some of the dielectric strips of a regulated amount of dielectric solvent such that there is 0À25% by weight of the solvent in the strips in the region of the partition faces. The solvent may be residual solvent from the casting of the strips, and the correct proportion is obtained by storing the strips in an atmosphere containing or lacking the solvent vapours. In such cases the parent capacitor contains the solvent and the heat generated by the cutting operation is sufficient to form the insulating zones. Alternatively the severed capacitors can be stored in a suitable atmosphere until at least the partition face zones include 0À25% solvent and the heat treatment can then be carried out. Preferably, as shown, the parent capacitor comprises alternate dielectric strips 1 containing solvent, e.g. cast polycarbonate strips and strips 6 containing no solvent, e.g. extruded polyethylene terephthalate strips. Both strips 1 and 6 have a metallized layer 7. Heat treatment of the partition faces 2 and 3 causes metallized layers 7 on strips 1 to break up into islands forming insulating borders 4 and 5. The capacitors have high breakdown resistance and good regenerative properties at the cut faces.

Title: Improvements in or relating to the coating of hollow bodies
IPC: H01J9/20
Filed: 1935-11-16
Abstract: A machine for coating a portion of the interior surface of a hollow body comprises means for depositing a coating material on a portion of the inner surface of said hollow body and means, operating alternately with said depositing means, for removing excess coating along an edge of said coated portion.  The machine illustrated, for use in coating the interior of electric lamp bulbs, comprises a rotary conveyer 10, carrying bulb holders 12, which is moved intermittently and passes through an oven 14.  A bulb 16 is placed <PICT:0448986/III/1> <PICT:0448986/III/2> <PICT:0448986/III/3> <PICT:0448986/III/4> <PICT:0448986/III/5> p  in a holder at A and moves first through the oven where it is heated to about 350 DEG  C. At B, a spray gun 17 enters the bulb and sprays a coating material on to the bowl portion thereof.  At D, compressed air is directed into the bulb to remove any loose particles of coating material, and at E and E<1>, wipers 20, 20<1> move into the bulb and are rotated at high speed to remove irregularities along the margin of the coating, giving a sharply defined border.  The bulb is removed at F.  At B, the bulb is lifted from the holder 12 and is gripped between rotatable and adjustable holders 18<1> and 25, the latter being driven so as to rotate the bulb, and the spray gun being moved into position with its nozzle 40 within the bulb.  The gun is mounted, for movement into and out of the bulb, on a reciprocated carriage 55, and, when in operative position, is oscillated, through a predetermined arc, about the curved surface 54 by the sliding movement of a plate 44.  A member 58 contacts with a valve-controlling lever 59 to cause the coating material to be discharged only while the nozzle is in its operative position, and when the nozzle is withdrawn the bulb is freed and again rests upon the holder 12.  Each wiper consists of flexible radial strips 65, e.g. of chamois leather, carried by a rapidly rotatable shaft 66, and these shafts are moved into and out of a bulb by arms 110, 111, operated by a rack 102 reciprocated by a driven cam 94, a rocker arm 96 and a bellcrank lever 99.  The bulb holder 12 comprises adjustable V-shaped supports 109<1> and 110<1>, and, during wiping, the bulb may be held down upon these supports by a spring-pressed finger 118 on a rocker arm 119.  When the rack 102 is moved forward to withdrawn the wiper members from the bulb, the roller 122 enters a notch 123 in the arm 119, thus allowing the finger 118 to lift and release the bulb. Specification 302,170, [Class 95], is referred to.

Title: Integrated circuit device with dielectric isolation and method of making the same
IPC: H01L21/762
Filed: 1966-07-15
Abstract: 1,114,798. Semi-conductor devices. WESTINGHOUSE ELECTRIC CORPORATION. 15 July, 1966 [9 Aug., 1965; 20 Aug., 1965 (2)], No. 31804/66. Heading H1K. Semi-conductor bodies 10a, b, c which comprise the elements of an integrated circuit device, are supported by a substrate 14 and are insulated from one another and from the substrate 14 at least partially by a layer 12 of material harder than that of the bodies 10a, b, c. The layer 12 may be, for example, of silicon carbide, the semi-conductor bodies being of silicon. The layer 12 is formed by deposition on a semi-conductor block (10), Fig. 2 (not shown) having grooves (11), formed by mechanical scribing or etching and corresponding in shape to the desired configuration of the layer 12, Fig. 5. The deposition of the layer 12 of silicon carbide is preferably by pyrolytic decomposition of methylsilanes or halogenated methylsilanes in an inert atmosphere, or alternatively SiCl 4  and propane may be caused to react together in hydrogen. The substrate 14 is then formed, e.g. by epitaxial deposition over the layer 12. The side of the resulting wafer remote from the substrate 14 is then ground or etched down to the level of the portions of the layer 14 in the bases of the grooves (11), so producing isolated semi-conductor bodies 10a, b, c. The relative hardness of the layer 12 provides a means of indicating when the grinding or etching process has reached the desired stage. The required P or N regions are diffused into the bodies 10a, b, c, which are then coated with an insulating layer 30 of, e.g. silicon dioxide, and the necessary ohmic contacts 24 are made through the layer 30. In order to improve the insulating properties of the layer 12, it may be composite, comprising a layer of silicon dioxide as well as the relatively hard layer of e.g. silicon carbide. In a second embodiment a composite layer is applied to an N-type semi-conductor body (50), Fig. 6 (not shown), having two sets of grooves (56, 58) of differing depth. An N+ layer (55), may be formed by epitaxy or diffusion on the body (50) prior to grooving. This may be replaced by a layer of Ta, Ti or Mo. After deposition of the substrate (64), Fig. 7 (not shown), the body (50) is ground or etched to the level of the relatively hard layer (60) at the bases of the deeper set of grooves (56). Subsequent controlled removal of more material to the required level is then relatively easy. Further embodiments are described, Figs 10, 11 (not shown), in which the semiconductor starting material, on which the relatively hard insulating layer is deposited, is first coated with alternate layers of insulator and semi-conductor. In these embodiments individual semi-conductor elements of the integrated circuit device are insulated from each other by silicon dioxide, groups of elements being insulated by relatively hard layers of silicon carbide. The groups may be separated into individual circuits.
